PENINGKATAN PEMAHAMAN RUMUS GEOMETRI MELALUI PENDEKATAN REALISTIK DI SEKOLAH DASAR
Abstract: The classroom action
research was carried out in order to : (1) make students easier in
understanding geometrical formulas; (2) raise the students’ achievement about
geometrical formula understanding and its application especially in the case of
plane area. : (3) motivate the students to understand geometrical formulas; and
(4) make the teaching-learning of understanding geometrical formulas would be
more effective. The research was carried out at the fith grade of state
elementary school called Terbantaman II in Depok Sleman Yogyakarta. The
Research was carried out in three cycles with each sycle consisting of
planning, actuating , observing and reflecting. The research data were
collected by instruments namely the achievement test, observation and interview.
Quantitative data were analysed by descriptive statistics; that was by
searching for the mean and by a test of difference, where as qualitative data
were analysed by an interpretative descriptive.
The research finding showed that the teaching of the plane area formulas
of rectangulars and triangles by realistic approach could raise the students’
eagerness and motivation in learning , understanding as well as applying the
plane area. It could be concluded that the teaching method applied could raise
students’ achievement in learning the plane area formula especially
rectangulars and triangels. In othe words, the teaching of geometrical formulas
by realistic approach could raise the students’ understanding about geometrical
formulas.
